CAN CSA C22.2 No. 80601-2-67-17: Technical Requirements for Oxygen Conserving Equipment in Medical Settings
A detailed examination of the Canadian adoption of IEC 80601-2-67 for oxygen-conserving device safety and performance
Scope and Purpose
CAN CSA C22.2 No. 80601-2-67-17 is the Canadian adoption of IEC 80601-2-67, a particular standard developed by the International Electrotechnical Commission (IEC) under the IEC 60601 series of medical electrical equipment standards. It specifies requirements for the basic safety and essential performance of oxygen conserving equipment (OCE) intended for use in healthcare facilities and home care environments. The standard applies to devices that deliver oxygen only during the inspiratory phase of the respiratory cycle, thereby conserving oxygen supply while maintaining adequate oxygen delivery to the patient.
The scope includes both stand-alone OCE and those integrated as subsystems within other medical devices, such as oxygen concentrators or ventilators. It does not apply to continuous-flow oxygen delivery devices, except where functional integration is present. Compliance with this standard is required for certification under the Canadian Electrical Code Part 2 (C22.2 series) and is often a prerequisite for Health Canada licensing or provincial regulatory acceptance.
Technical Requirements
Electrical Safety and Environmental Conditions
As a particular standard within the IEC 60601 family, CAN CSA C22.2 No. 80601-2-67-17 mandates compliance with the general safety requirements of CAN/CSA-C22.2 No. 60601-1 (IEC 60601-1, Edition 3.1 with Canadian deviations). Key electrical safety parameters include:
- Leakage current limits – Patient leakage current must not exceed 10 µA under normal conditions and 50 µA under single fault conditions.
- Dielectric strength – A hipot test of 1500 VAC for Class I equipment or 4000 VAC for Class II between mains and accessible parts.
- Protection against ingress of water and particulate – Minimum IP21 rating for home-use devices, with higher ratings for cleaning or sterilization.
- Environmental compatibility – Operation between 10 °C and 40 °C, 15%–95% relative humidity, and atmospheric pressure 700–1060 hPa.
Essential Performance and Accuracy
The core requirements focus on the device’s ability to reliably detect inspiration and deliver an accurate oxygen concentration, flow rate, and tidal volume. Table 1 summarizes the essential performance criteria.
| Parameter | Requirement | Test Condition |
|---|---|---|
| Oxygen delivery accuracy | ±10% of set flow or ±0.5 L/min, whichever is greater | At 23 °C ± 2 °C, standard pressure, using a certified oxygen analyzer |
| Inspiratory trigger sensitivity | Shall detect a patient effort equivalent to a flow of 0.1 L/min or less | Simulated breathing patterns per ISO 80601-2-67:2014 Annex BB |
| Response time from inspiration to delivery | Delay < 200 ms (usually < 100 ms for clinical acceptability) | Measured from onset of inspiratory flow to 90% of set oxygen flow |
| Oxygen concentration | Shall remain within ±3% of the set concentration (e.g., 30%–95%) | Stable breathing rate of 15 breaths/min, I:E ratio 1:2, FiO2 measured at patient interface |
| Alarm for loss of oxygen supply / high pressure | Visual and audible alarm within 10 seconds of condition | Simulated oxygen source pressure drop by 50% or overpressure to 120% of rated |
| Alarm for low delivered oxygen concentration | Visual and audible alarm when FiO2 drops more than 5% below set value for >5 seconds | Reduce oxygen supply concentration by 10% step |
Risk Management and Usability
The standard requires a documented risk management process per ISO 14971 (adopted as CAN/CSA ISO 14971-19). Manufacturers must identify hazards specific to oxygen conserving therapy, such as:
- Misdetection of breath leading to under‑ or over‑oxygenation.
- Blockage of the exhalation pathway causing barotrauma or CO₂ rebreathing.
- Fire/explosion risk due to oxygen enrichment in the presence of flammable materials.
- Battery failure causing unexpected shutdown (for portable devices).
Usability engineering (IEC 62366) is referenced to ensure that alarms are clear and that caregiver training can mitigate user errors.
Tip: Early engagement with a Notified Body (e.g., CSA Group, Intertek, SGS) during the design phase can help identify gaps in risk management documentation—addressing these before verification testing reduces costly redesign cycles.
Implementation Considerations
Adoption of CAN CSA C22.2 No. 80601-2-67-17 carries practical implications for product development and production. Key points include:
- Breath detection technology – Most OCE use pressure or flow sensors. The standard demands clear pass/fail criteria for sensitivity; manufacturers should select sensors with adequate dynamic range and fast response.
- Alarm prioritization – The standard mandates that high‑priority alarms (e.g., oxygen supply failure) must be visually distinct and audible at 65 dBA at 1 m, overriding lower‑priority signals. Implementation often requires a dedicated alarm manager module.
- Oxygen concentration verification – Devices must include a sensor or algorithm to verify delivered FiO₂. Any discrepancy beyond the tolerance must trigger an alarm. Some manufacturers incorporate a paramagnetic or ultrasonic sensor in the breathing circuit.
- Marking and instruction manual – Labels must follow CAN/CSA-C22.2 No. 0, showing the CSA mark, ratings, warnings (e.g., “No smoking – oxygen in use”), and cleaning instructions. The manual must include setup for home use and troubleshooting for common alarms.
Warn: A frequent non‑compliance issue is the lack of harmonization between the breath detection algorithm and the alarm response time. If the device takes > 200 ms to begin oxygen delivery, it fails the essential performance clause. Designers should allocate sufficient processing margin and test with variable breathing patterns.
Success: Products certified to CSA C22.2 No. 80601-2-67-17 are accepted across all Canadian provinces without additional electrical safety testing, streamlining market access. The CSA mark also facilitates recognition in other jurisdictions that adopt IEC 60601‑2‑67, such as the US (UL 60601‑2‑67) and the EU (EN 80601‑2‑67).
Compliance and Certification Process
To demonstrate conformity, manufacturers must submit a technical file containing:
- Detailed description of the OCE and its variants.
- Risk management file (ISO 14971).
- Test reports for electrical safety, essential performance, EMC (per CISPR 11 / CISPR 32 and IEC 60601‑1‑2), and usability.
- Software verification and validation (if software controlled).
- Manufacturing quality assurance (e.g., ISO 13485).
The certification body (e.g., CSA Group) will perform initial type testing, followed by factory inspections. The standard allows for “representative model” testing; however, if variants differ in breath detection hardware or alarm configuration, additional testing is required.
Danger: Failure to meet the oxygen accuracy alarm threshold can lead to unrecognized hypoxia. During certification testing, if the alarm does not activate within the specified time, the device is considered a critical safety hazard. Manufacturers should run extensive worst-case analyses for all environmental and patient conditions.
Once certified, the manufacturer must maintain ongoing compliance through periodic inspections and reporting of any significant design changes that could affect safety or essential performance.

Q: Does the standard apply to all types of oxygen concentrators?
A: It applies specifically to oxygen conserving equipment—devices that deliver oxygen only during inspiration. Traditional continuous‑flow oxygen concentrators, without a conserving valve or inspiratory detection, are not covered by this particular standard; they fall under the general IEC 60601‑1 and possibly IEC 80601‑2‑69 (for oxygen concentrators). However, if a concentrator includes a conserving mode, that mode must comply with 80601‑2‑67.

Q: Is compliance mandatory for marketing oxygen conserving devices in Canada?
A: Yes. All medical electrical equipment sold in Canada must comply with the applicable CSA C22.2 series standards, which are referenced in provincial electrical codes and by Health Canada’s Medical Devices Regulations. The required certification mark (e.g., CSA, cUL, cETL) demonstrates compliance with C22.2 No. 80601-2-67-17 for OCE.

Q: What are the typical enforcement changes expected in 2026?
A: As of 2026, the standard remains the current edition, but Health Canada is expected to strengthen post‑market surveillance for alarm‑related incidents. Manufacturers should ensure their risk management files include updated clinical hazard data and that periodic inspection audits by the certification body continue. No major amendments to the standard are anticipated before the next revision cycle (likely aligned with IEC 80601‑2‑67 Ed. 2).
